Examples of BAGPIPES fits for clumps selected from Hα, F275W, and F606W images. On the left: F275W image of a region in the tail of JO201; regions in golden yellow, pink and purple indicate an Hα clump, a UV clump and a star-forming complex, respectively. On the right: Examples of BAGPIPES fits to the photometry of the regions indicated on the image to the left; shaded region corresponds to the full range of the model spectra PDF and are plotted with the same color as the corresponding region in the image; black points with errorbars (generally too small to be seen) indicate the observed photometric fluxes in the five HST bands used in this work. Rectangles show the region between the 1% and 99% percentiles of the photometric fluxes fitted by BAGPIPES. Inset plots in the right panels show the posterior PDFs of mass-weighted ages (⟨t_⋆⟩), stellar masses (log M_⋆/M_⊙), SFRs, and A_V derived for each object.
